I just finished this One. Its Not very usable, but really nice to look at it. I had fun building this, and now i just wanted to share my result. It completely Made from acrylic, except the little wooden dowels.
Not usable? Great craftsmanship and clever as heck! I'm sure TSA would be interested. Even "as is", I think it certainly could do some serious damage.
Yes it is a lockback/backlock. I found the Plan for this at John Heisz Woodworking Website. http://www.ibuildit.ca/other projects/wood-knife-1.html Enjoy
Thank you for the link! Makes me want to try one made from steel. Edit: I was wondering what keeps the lockbar in place against the blade notch. I see now how it is done with a flat spring inserted in the end of the knife. I have wondered about that for years, but never took apart a knife to see how it was done.
